Periprosthetic Femur Fracture Clinical Evaluation

  •  

Periprosthetic Femur Fracture Xray / Diagnositc Tests

  • Consider ESR and CRP.  11% of periprosthetic fractures have concomitant infection.  (Chevillotte CJ, Ali MH, Trousdale RT, Larson DR, Gullerud RE, Berry DJ. Inflammatory laboratory markers in periprosthetic hip fractures. J Arthroplasty. 2009 Aug;24(5):722-7)

Periprosthetic Femur Fracture Classification / Treatment

  •  Vancouver classification
  • Type A=proximal to prosthesis (trochanteric region_:
  • Type B1=fracture around the stem or at the tip of the stem with component solidly fixed.
    -Treatment=plating vs allograft strut
  • Type B2=femor fracture around or just distal to a loose stem with adequate proximal bone stock.
    -Treatment= revision with long porous-coated cylindrical stem.
  • Type B3=femor fracture around or just distal to a loose stem with poor proxmial bone
    -Treatment: revision to long stem prosthesis +/- bone grafting/strutt. Consider proximal femoral replacement for elderly inactive patients. (Klein GR, JBJS 2005;87Am:1777).
  • Type C=distal to prosthesis, treated independently
  • Lateral locked plating with indirect reduction (Ricci WM, JOT 2006;20:190).
  • Age >70 with poor bone quality who require early mobilization = distal femur arthroplasty.
  • Periprosthetic supracondylar femoral fractures:  treatment options include conservative care,  retrograde intramedullary femoral nail,  locked or unlocked femoral plate, revision TKA.
